5.4.1. Renew the fuel filter
The maintenance intervals for the fuel filter are
dependent upon the purity of the diesel oil being
used and, if necessary, may have to be reduced
to 250 hours.
When working on the fuel system, do
not expose it to naked flames; do not
smoke.
Important !
Keep the entire area clean so that no dirt
reaches the fuel. Fuel particles may damage
the injection system.
– Shut off the fuel supply.

– Pull fuel feed line „1“ off fuel filter „2“ at both

the direction of fuel flow is as shown by the
arrows.
– Open up the fuel supply again and if necessary
operate the priming pump (chap. 4.1.3.).
– Run the engine briefly to check that there are
no leaks at the fuel filter and fuel lines.
